Scientists at NPL recently published findings on laser frequency stabilization, demonstrating an unprecedented level of ...

The length of this resonant cavity is crucial for controlling the target laser wavelength, called the resonance wavelength. Thus far, two types of GaN-based VCSEL structures have been developed ...

Physicists in Germany have developed a new technique to cool atoms with lasers. The method is applied to single atoms trapped in an optical cavity and is five times faster than conventional laser ...

Helium-neon lasers may be little more than glorified ... opposite the Brewster window and aligned to create a resonant optical cavity external to the tube. To switch mirrors easily, [Les] crafted ...

Lasers work by making energetic particles ... of high-energy ammonia molecules and a hollow enclosure called a resonance cavity to force microwaves to oscillate together. However, its power ...

CoreOptics' the feature product lines, encompassing a wide range of Horizontal Cavity Surface Emitting Lasers (HCSELs) and high-performance Resonant Cavity LEDs (ResoLight), position them as a key ...

As no light excitation is needed, the approach in principle circumvents the problems associated with continuous laser driving. This is the first work demonstrating such cavity control over ...

Such short-duration pulses are obtained through mode-locking, i.e. fixing the phase relationship between the longitudinal modes of the resonant cavity. All lasers have a range of frequencies or ...

Cavity ring down spectroscopy (CRDS) works by means of a laser pulse, beamed into a resonant cavity that is bounded by two of the highly reflective mirrors being tested. A detector is placed after the ...
